I agree with euro get a ro/di filter and make your own. I switched to red sea coral pro. Tank leveled out and has been great.

Hey yall
I have a radion pro with wide angle tier lenses on. I'm running them at 60 percent. I have a 70 gallon tank that I want to make SPS dominant. Every time I get a SPS piece, it keeps its color for 2 weeks then the tips begin to die and get brown. Later the whole coral becomes brown. I don't know what is wrong, are the radions too strong? Too weak? Any help will be awesome! Here are some pics of my sps

My parameters:

Cal - 450 (salifert)
Mag - 1355 (salifert)
Alk- 8.7 (salifert)
Nitrate - 4 (salifert)
Phosphate - 0 (Hanna checker)

What's the tank depth ? What's your water turnover ? Do you run a calcium reactor ? if not then how do you maintain Cal, Mag and DKH at stable parameters?

Can you post better pictures? It's hard to tell if your corals are browning OR if dead white tissue that has turned brown. Some more info on your system might also help (see the sticky).
